Problems solved by technology

[0006] The main purpose of the present invention is to propose a second-lined trolley for quickly pouring tunnels, aiming at solving the problem that the existing second-lined trolley walks window by window and manually switches concrete pump pipes layer by layer, resulting in longer pouring time and frequent Replace the pump tube; at the same time, the wooden formwork of the end formwork is not solidly reinforced, and it is easy to run out of the mold and leak slurry, and it is inconvenient to remove and install the technical problem of the waterstop

Embodiment 1

[0063] see Figure 1-Figure 10 :

[0064] The trolley frame 100 is fitted with a primary lining support arch at the top;

[0065] The trackless traveling assembly 200 is installed under the trolley frame 100;

[0066] The telescopic steel end form 300, one end of the trolley frame 100 is installed and connected by a soft lap, the other end is provided with a telescopic steel end form 300, and the telescopic steel end form 300 is connected to the trolley frame 100 through a hinge 310 ;

[0067] The double-pump layer-by-layer full-silo distribution assembly 400 is installed on the trolley frame 100. The discharge ports 470 of the double-pump layer-by-layer full-silo distribution assembly 400 are distributed on both sides of the trolley frame 100. The discharge speed of the discharge port 470 is the same;

[0068] The high-frequency flat vibrator 500 is installed between the discharge ports 470 provided on the trolley frame 100;

[0069] The automatic plug-in vibrating devic...

Embodiment 2

[0073] see again Figure 1-Figure 10 :

[0074] When it is necessary to calculate the safety of the trolley, in order to ensure the pouring volume of 60 cubic meters per hour, the pouring speed and height direction are calculated with the 12-meter trolley, and the average thickness of the surrounding rock is calculated as 0.7m. For the sake of safety, the trolley structure is designed according to the pouring speed of 4m / h, and the check calculation is carried out.

[0075] Load calculation

[0076] Based on the lining thickness of 70cm and the first version of lining of 12m, the amount of concrete poured at one time is 300.6m3.

[0077] (1) Side form load

[0078] Standard value of side mold load:

[0079] The standard value of the pressure of the newly poured concrete on the side of the formwork 720:

[0080] F=0.22×r c ×t 0 ×β 1 ×β 2 ×V 12 =0.22×25×6×1.2×1.15×3 12 =78.9KN / m 2

[0081] F=r c ×H=25×10.8=270KN / m 2

[0082] Take the smaller of the two, so the m...

Embodiment 3

[0116] see again Figure 1-Figure 10 :

[0117] The trackless traveling assembly 200 includes a traveling mechanism 210, a first oil cylinder 220, a second oil cylinder 230 and a support 240. The four first oil cylinders 220 are respectively connected to the front and rear sides of the trolley by bolts. The output end of the first oil cylinder 220 is connected with a support 240 through bolts, and the front end and rear end of the bottom of the trolley are respectively connected with a traveling mechanism 210 and a second oil cylinder 230 through bolts. The output end of the second oil cylinder 230 A running mechanism 210 is connected;

[0118] The single step distance of trackless walking is 1.5 meters. The walking system is equipped with a remote control, which can be operated by a single person to realize the functions of the overall translation, offset, and U-turn of the trolley. The specific working steps are as follows:

[0119] S1, extending the first oil cylinder 220...

Abstract

The invention belongs to the technical field of tunnel engineering construction, and particularly relates to a secondary lining trolley for rapidly pouring a tunnel, which comprises a trolley frame, a primary lining support arch frame and a secondary lining support arch frame, the trackless walking assembly is mounted below the trolley frame; the end head of one end of the trolley frame is connected through a soft lap joint, the other end of the trolley frame is provided with the telescopic steel end mold, and the telescopic steel end mold is connected with the trolley frame through a hinge; the double-pump layer-by-layer full-bin material distribution assembly is installed on the trolley frame, discharging ports of the double-pump layer-by-layer full-bin material distribution assembly are distributed in the two sides of the trolley frame, and the discharging speeds of the discharging ports in the two sides are the same. According to the secondary lining trolley for rapidly pouring the tunnel, lining pouring can be carried out through simultaneous material distribution of double pumps in a whole bin layer by layer, pipe connection can be carried out at a time till pouring is completed, pump pipes do not need to be replaced, workers only need to easily operate valves, and the telescopic steel end molds are connected through hinges and are quite convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering construction, in particular to a secondary lining trolley for rapidly pouring tunnels. Background technique [0002] With the increasing prosperity of the national economy and the rapid progress of science, the proportion of tunnels in various traffic routes in China is increasing day by day. Tunnels are underground linear engineering buildings with high construction difficulty, high technical standards, and strong concealment. Once quality problems occur, it is extremely difficult to maintain later, so tunnel construction has received more and more attention. And the quality of the secondary lining, which plays a decisive role in the safety of the tunnel structure, has attracted more and more attention. The hydrogeological conditions in the tunnel are complex. If the impermeability of the secondary lining concrete is poor, leakage will occur. Coupled with the continuous strengthening ...
